My inventionjhas for its object to improve the construction of my harvester for which Letters Patent No. 120,027, were issued to me October 17, 1871, so as to make it a selfbinder, `and otherwise ,make it more effective in-operation 5 and it consists in the combination of a block, crossed or diagonal rods, and their supportsorequivalentswith thedriviug-pitman and sickle-bar5in the combination of the end-A less chain, chain-wheels, chain pulleys, chainpulley rods, ilanged wheel with its gates andv springs, and the iianged lever with each-other and `witl the driving mechanism, for the purpose of raising the gavel `into contact with lthe binding device; in the employment in ay grain-binding harvester of a spiral-gear wheel,

and a lspiral-toothed scroll provided with internally-projecting pins or teeth, for the purpose of twisting bands upon and around the grain-bundles; in the combination of frame, shaft, spiral-gear wheel, spiral-toothed scroll, supporting rollers, hook, sliding block, and spiral spring with eachother, for the purpose ot'forming a straw band around -tne gavelv while` being held and rotated by the endless chain; and in the combination ofthe leverchain and lever for raising the cutter-bar with the cutter-bar andwith the pi'voted `seat and pivoted standard, as hereinafter morev fully described. l A

A represents the tongue, inthe rear part of which is a bear-ing for the axle or drivin g-shaft` B. C is the outer and'D is the inner drivewheel, one of which may be connected with the axle B rigidly, and the other with a pawland-ratchet wheel or other' clutch, or both may be connected with said axle with pawland-ratchet wheels or other clutches. The inner drive-wheel--D may be made somewhat larger than the outer drive-wheel C to throw the work of driving the cutters mainly upon the outer wheel and thus counteract the side `draft of theniachine. E is a box for receivingandiprotectingthe gearing for driving the cutter-mathe rear part of which i'si'igidly attached tothe tongue A, and its forward part ,isconnected with said tongueby an arm', e', cast` solid upon-.said box E. The box E has` also lugs cast upon it Vto receive various arms.`rods, and braces. To the driving-shaft B, at the inner side ofthe outer .wheel C, is attached a cup shaped' gearwheel, F, which' enters a recess in the'outer side of the box E, v'andthe teeth of which mesh into the teeth ofthe small gear-wheel G, attached to the short shaft H, placed at right angles to the shaftB, and which worksin bearings inthe box E. To the shaft H is also attached a large cup-shaped `gear-wheel, I, which en'- ters the cavity ot' the 'wheel F, and the teethvof which mesh into the teeth of the small gearwheel J, attachedto therear end ofthe shaft K, placed parallel with the shaftB, and which ,revolves in bearings inthe lower part of the box E. To the 'forward end of the shaft K is attached a small crank-wheel, L, to which is pivoted the end of lthe pitman M that drives thecutter-bars. Theouter end of the pitman M is pivoted to the block N, about midway between its center and inner end. To the block N, about midway between its 'oenteraud outer-end, is'pivoted the inner end ofthe.

sickle-bar O. To the ends of the block N are pivoted-the lower ends of the two rods P,

which cross each other, and the'npper ends of which are pivoted to the ends of the block or cross-head Q, ywhich is of about the same length as the block N, and which is rigidly attached: yto the `upper end of a short stud, It, rigidly attachedto the inner end of the cutterbar S; By this arrangement the sickle-bar O will work equally well whatever be the inclination of the eutterbar S and platform T. The cutter-bar S and platform T are connected with the frame-work of the machine by the rod U and brace V. The end of the rod U is pivoted to thecutter-bar S, and the end ofthe brace V is pivoted to the forward end of a projection or finger formed upon the inner end of said cutter-bar. The outer end of the rod U passes through a projection upon the forward end of the box E, and is secured by a nut. The brace V inclines inward, and its other end is pivoted to the end of the rod U. The ends of the rod U and brace V are further supported by a brace, W, the forward end of which is connected with the end of the rod U and its rear end is` bolted to thev side of the box E. .X is a lever, the end of which is piv.- oted to the forward end of the finger or guard of the cutter-bar S, to which the brace V is pivoted.- The lever X,at its angle, is pivoted to the ro'd U, and its other end projects upward into such a position that it may be conveniently reached and operated by the driver from his seat to raise and lower the points of thesickles, as may be desired. Y is a bar sliding along the sideof the lever X, which is raised and lowered by a small bent spring-lever, Z, pivoted to the upper part of thesaid lever X. .The lower end of the bar Y enters notches in the edge of the rounded forward end of the brace A1, `whichis placed upon the rod U at the side of the lever X, and the rcarend of which -is attached to the rear part of the box E. B1 is the drivers seat, which is pivoted to the upper end of the standard Cx the lower end of which is pivoted to tongue A.' To the seat B1 is also pivoted the upper end of the bent lever D1, which is pivoted at its bend to thetongue A a littleinfront of the pivoting-point of the standard G1. The

lower arm ofthe lever Dl projects forward, and has a hook formed upon its end to enter alink of the chain El, which passes around a friction-pulley placed upon'the rod U. The end of the .chain El is attached to the end of the lever F1, which is pivoted to the inner end of the .cutter-bar S, and has a shoulder formed upon it so that the cutter-bar S may be raisedv by lowering the said lever. G-1 lis a standard rigidly attached to the tongue A, and which has a foot-rest attached to or formed upon its upper end, so that the driver, by resting his foot against the said standardfcanforce the seat Bl back to operate the levers D1 F1 to raise the cutter-bar and its attachments for passing obstructions, &c. To the rear end of the shaft H is swiveled the end` of a shaft, Hl. To the adjacent ends of the shafts E H1 are attached, respectively, the bevel-gear wheels I1 J1, the teeth of which mesh into each other, and which communicate motion from the said shaft H to the said shaft H1. .The shaft H1 is made in two parts, one of which slides into the other so that the said` shaft may aecommodate itself in length to the position of the platform T. To the other en d of the extension vshaft H1 is attached a bevelgear wheel, K1, the teeth of which mesh into the teeth oi.' the bevel-gear wheel L1, attached to the end oi' the shaft M'. The adjacent ends of the shafts H1 M' 4are' swiveled to each other. By this construction the shaft H1 serves to communicate motion from the sh aft H to the shaft M', and atthe-same time is supported by the said shafts H M'. The shaft M' revolves in bear? ings attached to the inner forward part of the platform T, and to its forward part is attached a chain-wheel, N', around which passes the endless chain or band 0', .which also passes around the pulley P' pivoted to the frame Q', which is 'rigidly attached to the upper end of. the standard lt', the lower end of which is securely attached to the rear bearings of the shaftM', or to the platform T. The endless chain or band O' also passes around the chainpulleys S' T', pivoted, respectively, to the bars U' V'. The lower end ofthe bar U' is pivoted to the platform T at the inner side of the chainwheel N', and is designed to'lieep the pulley S' in place, the said pulley acting' as an idler to keep the chain or band O'vta-ut. The bar V' is pivoted to the forward bearing ofthe shaft M', and upon its end is formed an arm projecting at right angles, which enters -a groove in the face of the wheel W', attached to the forward end of the shaft M'. The face of the wheel W' has a continuous flange, w1, around its outer edge, and' a ila-nge, 'm2, between the outer ange and the central core or j hub w3. The middle flange w2 has two openings formed through it for the passage ofthe end of the arm V', so that, by allowing said end to pass into the inner space or groove, the roller T' may be raised to raise the gavel to bel bound, lthe upper part of the chain or band Q' forming'a loop, as shown in Fig. 2, to hold and support the said gavel and, by allowing said end to pass into the outer `space or groove, the roller T' will drop to the platform T, t'o

allow another gavel to be swept by the rake l over the rollers T' S' upon the chain or band O' to be raised by the rise of the roller 'l'.

. The openings through the flan ge w? are-closed by the two outer gates 1 2 and the two inner gates 3 4. The outer gates are arranged to open in oppositedreetions, as shown in Fig. 5, and their pivots pass vthrough the .wheel W', and have crank-arms .formed upon their outer ends, against ywhich rest the ends of a spring X', `attached to the wheel W', and which holds the gates l 2 shut. -The inner gates 3 4 open in an opposite direction from f each other and from their. yeorrespondin g gates l 2, are pivoted to thewhecl NV', and have cranks formed upon theprojectingcnds ofthe said pivots, againstwhich rest the ends of a. spring, Y', attached to the wheel W', and which holds the said vgates closed. 'in' is a lever, the,l lower end of which is bent inward slightly, as shown, in Figs. 3 and 4,and. is

pivoted to the platform T beneath the forward- `part of the wheel W' so that the saidv lever may drop away from the said wheel by its own weight. The lower part of the lever Z' is enlarged to cover the forward side of the wheel W', and upon said enlarged part, near its outer edge, is formed a curved ange al,

with an inclined forward end, in such a position that when the lever Z' is held up against the wheel W' the said iiange 21 will strike against the crank-pivot of the gate 1` that opens toward the advancing end of the rod 'V' and open said gate to allow the end of the said rod to pass through, which end forces back the corresponding inner gate 3 and passes into the inner groove, raising the roller 'l" and the gavel. Upon the lower enlarged part of the lever Z' is formed, near the center of said part, and in such a position as to strike the crank-pivot of the inner gate athat opens toward the end of the rod V' when in the inner `groove, a curved flange, z2, to openthe said inner gate 4 and allow the said endof the rod V' to pass out into the outer groove to lower the roller T' and chain or band, O', to receive another gavel. 'lhe'upper end-of the lever Z' projects into such a position that it may be conveniently' reached and operated by the driver from his seat. To the rear end of the chain-wheel N' is attached or upon it is formed a bevel-gearfwheel, A2, the teeth of which mesh into-the teeth of the small bevelgear wheel B2 attached to the lower end of the shaft C2, lto the upper end of which is attached a larger bevel-gear wheel, D2. The teeth of the bevel-gear wheel D2 mesh into the teeth of the smaller bevelfgear wheel E2 attached to the Ashort shaft F2, which revolvesin bearings in theframe Q'. The shaft O2 is slightly inclined forward to bring thel shaft F2 directly overthe chain or band O'. To the sha-ft F2, within the frame Q', is attached a cylinder, G2, having a spiral iiange formed upon it, makingA about two turns, andupon the edge of which are formed gear-teeth, thus forming a spiralgear wheel. H2is a spiralgea-r scroll similar to the spiral-gear wheel G2, into the teeth of which the teeth of the .said spiral scroll mesh. The spiral-scroll kept from `longitudinal movement by the ends, of the frame Q', against which the ends of, the

said wheel H2 rest. Upon the inner surface of the toot-hed scroll H2 are formed internallyprojecting pins or teeth, as shown in Figs. 2, 7, and 8,- to take hold of the band, and twist it as it is passing through said scroll. J2 is a hook attached to or formed upon the block K2, that slides up and down in a groove in the inner end part of the frame Q', and is held down to its placeby a spiral spring, L2, placed upon a stem formed upon the upper end of the said sliding block K2.

By this construction, as' the gavel is raised by the rise of the pulley and rod T' V' itreceives a continuous rotary motion'from the movement of the endless chain or band O'.

As the gavel revolves the hook J2 takes up a I little of the straw which is caught by the pointed inner end of the spiral scroll H2, and twisted while being carried through said scroll, which process, being continued, forms a continuous rope of the straw of the gavel itself. The straw rope, while being formed, rests in a groove of the chain or band O', the chainwheels N' P' and pulleys S' T' being grooved accordingly. As the forward end of the rope being formed cornes around to the hook J2, it passes beneath and raises the sliding block K2, which raises the hook J2 so that it cannot take up any more straw, allowing the ends of the straws already taken up to lbe twisted in with the rope already formed, making it conv tinuous. The roller T' and'arm V' are now lowered, leaving the bundle suspended by its band, which passes through the spiral scroll H2. The weight of the bundle now draws down the band so thatthe pointed forward end of the scroll H2 passes above said band, and thus runs the scroll out of the band, allowing the bundle to drop.

It will beobserved that only the butt en ds of the straws are twisted, leaving their heads in place upon the bundle, and unshelled.

Having thus described my invention, I claim as new and kdesire to secure by Letters Patent- 4 1. ',lhecombination of the bloclr N, crossed or diagonal pivoted rods P and support Q R, or` equivalent with the drivin g-pitman M and sickle-bar O, substantially as herein shown and described, and for the purpose set forth.
